Low price 21700 battery china
1. The energy density of the 21700 battery is higher than that of the well-known 18650 battery. The number of single cells in use can be greatly reduced, and the cost will be reduced after grouping. , a 18650 battery capacity is about 2600-3600 mAh, a 21700 battery supports more than 4000 mAh, and 217005000mAh has appeared on the market. And the larger capacity is increasingly beneficial to extend the battery life of modern devices.
2. The single volume of the rechargeable battery is increased by 35%. The 21700 battery manufacturer tells you that taking the 21700 rechargeable battery produced by a car company as an example, from 18650 to 21700, the energy of a single battery can be increased by 34.8ah, an increase of 35%.
3. The net weight of the system software is estimated to be reduced by 10%. The total capacity is more than 21,700. With the increase of single volume and the increase of single energy ratio, the total number of batteries required under the same kinetic energy can be reduced by about 1/3. The 21700 battery manufacturer tells you that the total number of metal components and electrical components selected for the battery pack can be reduced.
